manual: use one-line titles instead of two-line titles (trivial)
Asciidoc supports two syntaxes for section titles: two-line titles (title
plus underline consisting of a particular symbol), and one-line titles
(title prefixed with a specific number of = signs).
The two-line title underlines are:
Level 0 (top level): ======================
Level 1: ----------------------
Level 2: ~~~~~~~~~~~~~~~~~~~~~~
Level 3: ^^^^^^^^^^^^^^^^^^^^^^
Level 4 (bottom level): ++++++++++++++++++++++
and the one-line title prefixes:
= Document Title (level 0) =
== Section title (level 1) ==
=== Section title (level 2) ===
==== Section title (level 3) ====
===== Section title (level 4) =====
The buildroot manual is currenly using the two-line titles, but this has
multiple disadvantages:
- asciidoc also uses some of the underline symbols for other purposes (like
preformatted code, example blocks, ...), which makes it difficult to do
mass replacements, such as a planned follow-up patch that needs to move
all sections one level down.
- it is difficult to remember which level a given underline symbol (=-~^+)
corresponds to, while counting = signs is easy.
This patch changes all two-level titles to one-level titles in the manual.
The bulk of the change was done with the following Python script, except for
the level 1 titles (-----) as these underlines are also used for literal
code blocks.
This patch only changes the titles, no other changes. In
adding-packages-directory.txt, I did add missing newlines between some
titles and their content.

=== Infrastructure for packages with specific build systems
|
2011-10-10 10:46:39 +02:00
|
|
|
|
|
|
|
By 'packages with specific build systems' we mean all the packages
|
|
|
|
whose build system is not one of the standard ones, such as
|
|
|
|
'autotools' or 'CMake'. This typically includes packages whose build
|
|
|
|
system is based on hand-written Makefiles or shell scripts.

The Makefile begins on line 7 to 11 with metadata information: the
|
2011-10-10 10:46:39 +02:00
|
|
|
version of the package (+LIBFOO_VERSION+), the name of the
|
2013-09-06 08:14:15 +02:00
|
|
|
tarball containing the package (+LIBFOO_SOURCE+) (xz-ed tarball recommended)
|
|
|
|
the Internet location at which the tarball can be downloaded from
|
2012-12-30 11:47:21 +01:00
|
|
|
(+LIBFOO_SITE+), the license (+LIBFOO_LICENSE+) and file with the
|
|
|
|
license text (+LIBFOO_LICENSE_FILES+). All variables must start with
|
|
|
|
the same prefix, +LIBFOO_+ in this case. This prefix is always the
|
|
|
|
uppercased version of the package name (see below to understand where
|
|
|
|
the package name is defined).
|
2011-10-10 10:46:39 +02:00
|
|
|
|
2013-02-25 12:31:31 +01:00
|
|
|
On line 12, we specify that this package wants to install something to
|
2011-10-10 10:46:39 +02:00
|
|
|
the staging space. This is often needed for libraries, since they must
|
|
|
|
install header files and other development files in the staging space.
|
|
|
|
This will ensure that the commands listed in the
|
|
|
|
+LIBFOO_INSTALL_STAGING_CMDS+ variable will be executed.
|
|
|
|
|
2013-02-25 12:31:31 +01:00
|
|
|
On line 13, we specify that there is some fixing to be done to some
|
2013-01-30 03:46:40 +01:00
|
|
|
of the 'libfoo-config' files that were installed during
|
|
|
|
+LIBFOO_INSTALL_STAGING_CMDS+ phase.
|
|
|
|
These *-config files are executable shell script files that are
|
|
|
|
located in '$(STAGING_DIR)/usr/bin' directory and are executed
|
|
|
|
by other 3rd party packages to find out the location and the linking
|
|
|
|
flags of this particular package.
|
|
|
|
|
|
|
|
The problem is that all these *-config files by default give wrong,
|
|
|
|
host system linking flags that are unsuitable for cross-compiling.
|
|
|
|
|
|
|
|
For example: '-I/usr/include' instead of '-I$(STAGING_DIR)/usr/include'
|
|
|
|
or: '-L/usr/lib' instead of '-L$(STAGING_DIR)/usr/lib'
|
|
|
|
|
|
|
|
So some sed magic is done to these scripts to make them give correct
|
|
|
|
flags.
|
2013-02-07 13:35:03 +01:00
|
|
|
The argument to be given to +LIBFOO_CONFIG_SCRIPTS+ is the file name(s)
|
2013-01-30 03:46:40 +01:00
|
|
|
of the shell script(s) needing fixing. All these names are relative to
|
|
|
|
'$(STAGING_DIR)/usr/bin' and if needed multiple names can be given.
|
|
|
|
|
2013-02-07 13:35:04 +01:00
|
|
|
In addition, the scripts listed in +LIBFOO_CONFIG_SCRIPTS+ are removed
|
|
|
|
from +$(TARGET_DIR)/usr/bin+, since they are not needed on the target.
|
|
|
|
|

.Config script: 'divine' package
|
|
|

================================
|
2013-01-30 03:46:40 +01:00

|
Package divine installs shell script '$(STAGING_DIR)/usr/bin/divine-config'.
|
|
|
|
|
2013-08-09 12:16:48 +02:00
|
|
|
So its fixup would be:
|
2013-01-30 03:46:40 +01:00
|
|
|
|
2013-08-09 12:16:48 +02:00

|
|
|
================================
|
2013-01-30 03:46:40 +01:00

Package imagemagick installs the following scripts:
|
|
|
|
'$(STAGING_DIR)/usr/bin/{Magick,Magick++,MagickCore,MagickWand,Wand}-config'

|
|
On line 14, we specify the list of dependencies this package relies
|
2011-10-10 10:46:39 +02:00
|
|
|
on. These dependencies are listed in terms of lower-case package names,
|
|
|
|
which can be packages for the target (without the +host-+
|
|
|
|
prefix) or packages for the host (with the +host-+) prefix).
|
|
|
|
Buildroot will ensure that all these packages are built and installed
|
|
|
|
'before' the current package starts its configuration.
|
|
|
|
|
2013-02-25 12:31:31 +01:00
|
|
|
The rest of the Makefile, lines 16..29, defines what should be done
|
2012-12-30 11:47:21 +01:00
|
|
|
at the different steps of the package configuration, compilation and
|
|
|
|
installation.
|
2011-10-10 10:46:39 +02:00
|
|
|
+LIBFOO_BUILD_CMDS+ tells what steps should be performed to
|
|

|
build the package. +LIBFOO_INSTALL_STAGING_CMDS+ tells what
|
|
|
|
steps should be performed to install the package in the staging space.
|
|
|
|
+LIBFOO_INSTALL_TARGET_CMDS+ tells what steps should be
|
|
|
|
performed to install the package in the target space.
|
|
|
|
|
|
|
|
All these steps rely on the +$(@D)+ variable, which
|
|
|
|
contains the directory where the source code of the package has been
|
|
|
|
extracted.
|
|
|
|
|
2016-01-21 22:23:38 +01:00
|
|
|
On lines 31..43, we define a user that is used by this package (e.g.
|
|
|
|
to run a daemon as non-root) (+LIBFOO_USERS+).
|
|
|
|
|
|
|
|
On line 35..37, we define a device-node file used by this package
|
2012-12-30 11:47:21 +01:00
|
|
|
(+LIBFOO_DEVICES+).
|
|
|
|
|
2016-01-21 22:23:38 +01:00
|
|
|
On line 39..41, we define the permissions to set to specific files

installed by this package (+LIBFOO_PERMISSIONS+).
|
|
|
|
|
2013-04-12 09:14:18 +02:00
|
|
|
Finally, on line 43, we call the +generic-package+ function, which
|
2011-10-10 10:46:39 +02:00
|
|
|
generates, according to the variables defined previously, all the
|
|
|
|
Makefile code necessary to make your package working.

manual: use one-line titles instead of two-line titles (trivial)
Asciidoc supports two syntaxes for section titles: two-line titles (title
plus underline consisting of a particular symbol), and one-line titles
(title prefixed with a specific number of = signs).
The two-line title underlines are:
Level 0 (top level): ======================
Level 1: ----------------------
Level 2: ~~~~~~~~~~~~~~~~~~~~~~
Level 3: ^^^^^^^^^^^^^^^^^^^^^^
Level 4 (bottom level): ++++++++++++++++++++++
and the one-line title prefixes:
= Document Title (level 0) =
== Section title (level 1) ==
=== Section title (level 2) ===
==== Section title (level 3) ====
===== Section title (level 4) =====
The buildroot manual is currenly using the two-line titles, but this has
multiple disadvantages:
- asciidoc also uses some of the underline symbols for other purposes (like
preformatted code, example blocks, ...), which makes it difficult to do
mass replacements, such as a planned follow-up patch that needs to move
all sections one level down.
- it is difficult to remember which level a given underline symbol (=-~^+)
corresponds to, while counting = signs is easy.
This patch changes all two-level titles to one-level titles in the manual.
The bulk of the change was done with the following Python script, except for
the level 1 titles (-----) as these underlines are also used for literal
code blocks.
This patch only changes the titles, no other changes. In
adding-packages-directory.txt, I did add missing newlines between some
titles and their content.

+host-generic-package+ macro is used for host packages, natively compiled
|
2014-12-19 08:12:33 +01:00
|
|
|
for the host. It is possible to call both of them in a single +.mk+

file: once to create the rules to generate a target
|

|
|
|
package and once to create the rules to generate a host package:
|
|
|
|
|
|
|
|
----------------------
|
2012-07-03 00:07:08 +02:00
|
|
|
$(eval $(generic-package))
|
2012-07-03 00:05:46 +02:00
|
|
|
$(eval $(host-generic-package))
|
2011-10-10 10:46:39 +02:00
|
|
|
----------------------
|
|
|
|
|
|
|
|
This might be useful if the compilation of the target package requires
|
|
|
|
some tools to be installed on the host. If the package name is
|
|
|
|
+libfoo+, then the name of the package for the target is also
|
|
|
|
+libfoo+, while the name of the package for the host is
|
|
|
|
+host-libfoo+. These names should be used in the DEPENDENCIES
|
|
|
|
variables of other packages, if they depend on +libfoo+ or
|
|
|
|
+host-libfoo+.
|
|
|
|
|
2012-07-03 00:07:08 +02:00
|
|
|
The call to the +generic-package+ and/or +host-generic-package+ macro *must* be
|
2012-07-03 00:05:46 +02:00
|
|
|
at the end of the +.mk+ file, after all variable definitions.
|
2011-10-10 10:46:39 +02:00
|
|
|
|
2012-07-03 00:07:08 +02:00
|
|
|
For the target package, the +generic-package+ uses the variables defined by
|
2011-10-10 10:46:39 +02:00
|
|
|
the .mk file and prefixed by the uppercased package name:
|
2012-07-03 00:05:46 +02:00
|
|
|
+LIBFOO_*+. +host-generic-package+ uses the +HOST_LIBFOO_*+ variables. For
|
2011-10-10 10:46:39 +02:00
|
|
|
'some' variables, if the +HOST_LIBFOO_+ prefixed variable doesn't
|
|
|
|
exist, the package infrastructure uses the corresponding variable
|
|
|
|
prefixed by +LIBFOO_+. This is done for variables that are likely to
|
|
|
|
have the same value for both the target and host packages. See below
|
|
|
|
for details.
|
|
|
|
|
|
|
|
The list of variables that can be set in a +.mk+ file to give metadata
|
|
|
|
information is (assuming the package name is +libfoo+) :
|
|
|
|
|
|
|
|
* +LIBFOO_VERSION+, mandatory, must contain the version of the
|
|
|
|
package. Note that if +HOST_LIBFOO_VERSION+ doesn't exist, it is
|
|
|
|
assumed to be the same as +LIBFOO_VERSION+. It can also be a
|
2012-02-06 21:41:08 +01:00
|
|
|
revision number, branch or tag for packages that are fetched
|
2011-10-10 10:46:39 +02:00
|
|
|
directly from their revision control system. +
|
2012-02-06 21:41:08 +01:00
|
|
|
Examples: +
|
|
|
|
+LIBFOO_VERSION = 0.1.2+ +
|
|
|
|
+LIBFOO_VERSION = cb9d6aa9429e838f0e54faa3d455bcbab5eef057+ +
|
|
|
|
+LIBFOO_VERSION = stable+
|
2011-10-10 10:46:39 +02:00
|
|
|
|
2015-03-29 19:33:20 +02:00
|
|
|
* +LIBFOO_SOURCE+ may contain the name of the tarball of the package,
|
|
|
|
which Buildroot will use to download the tarball from
|
|
|
|
+LIBFOO_SITE+. If +HOST_LIBFOO_SOURCE+ is not specified, it defaults
|
|
|
|
to +LIBFOO_SOURCE+. If none are specified, then the value is assumed
|
|
|
|
to be +libfoo-$(LIBFOO_VERSION).tar.gz+. +
|
2011-10-10 10:46:39 +02:00
|
|
|
Example: +LIBFOO_SOURCE = foobar-$(LIBFOO_VERSION).tar.bz2+
|
|
|
|
|
2013-01-06 06:22:42 +01:00
|
|
|
* +LIBFOO_PATCH+ may contain a space-separated list of patch file
|
2015-03-29 19:33:20 +02:00
|
|
|
names, that Buildroot will download and apply to the package source
|
|
|
|
code. If an entry contains +://+, then Buildroot will assume it is a
|
|
|
|
full URL and download the patch from this location. Otherwise,
|
|
|
|
Buildroot will assume that the patch should be downloaded from
|
|
|
|
+LIBFOO_SITE+. If +HOST_LIBFOO_PATCH+ is not specified, it defaults
|
|
|
|
to +LIBFOO_PATCH+. Note that patches that are included in Buildroot
|
2013-01-06 06:22:42 +01:00
|
|
|
itself use a different mechanism: all files of the form
|
2015-03-29 19:33:23 +02:00
|
|
|
+*.patch+ present in the package directory inside
|
2012-11-27 12:59:17 +01:00
|
|
|
Buildroot will be applied to the package after extraction (see
|
2013-01-06 06:22:42 +01:00
|
|
|
xref:patch-policy[patching a package]). Finally, patches listed in
|
|
|
|
the +LIBFOO_PATCH+ variable are applied _before_ the patches stored
|
|
|
|
in the Buildroot package directory.
|

|
|
|
|
2012-06-17 13:53:59 +02:00
|
|
|
* +LIBFOO_SITE+ provides the location of the package, which can be a
|
|
|
|
URL or a local filesystem path. HTTP, FTP and SCP are supported URL
|
2015-09-28 18:10:33 +02:00
|
|
|
types for retrieving package tarballs. In these cases don't include a
|
|
|
|
trailing slash: it will be added by Buildroot between the directory
|
|
|
|
and the filename as appropriate. Git, Subversion, Mercurial,
|
2012-06-17 13:53:59 +02:00
|
|
|
and Bazaar are supported URL types for retrieving packages directly
|
2013-12-05 18:20:45 +01:00
|
|
|
from source code management systems. There is a helper function to make
|
2014-06-02 17:55:59 +02:00
|
|
|
it easier to download source tarballs from GitHub (refer to
|
2013-12-05 18:20:45 +01:00
|
|
|
xref:github-download-url[] for details). A filesystem path may be used
|
2012-06-17 13:53:59 +02:00
|
|
|
to specify either a tarball or a directory containing the package
|
|
|
|
source code. See +LIBFOO_SITE_METHOD+ below for more details on how
|
|
|
|
retrieval works. +
|
|
|
|
Note that SCP URLs should be of the form
|
|
|
|
+scp://[user@]host:filepath+, and that filepath is relative to the
|
|
|
|
user's home directory, so you may want to prepend the path with a
|
|
|
|
slash for absolute paths:
|
2012-02-06 21:41:08 +01:00
|
|
|
+scp://[user@]host:/absolutepath+. +
|
|
|
|
If +HOST_LIBFOO_SITE+ is not specified, it defaults to
|
2012-11-07 00:10:43 +01:00
|
|
|
+LIBFOO_SITE+.
|
2012-02-06 21:41:08 +01:00
|
|
|
Examples: +
|
|
|
|
+LIBFOO_SITE=http://www.libfoosoftware.org/libfoo+ +

|
|
|
|
2016-08-23 14:19:46 +02:00
|
|
|
* +LIBFOO_DL_OPTS+ is a space-separated list of additional options to
|
|
|
|
pass to the downloader. Useful for retrieving documents with
|
|
|
|
server-side checking for user logins and passwords, or to use a proxy.
|
|
|
|
All download methods valid for +LIBFOO_SITE_METHOD+ are supported;
|
|
|
|
valid options depend on the download method (consult the man page
|
|
|
|
for the respective download utilities).
|
|
|
|
|
2015-03-29 19:33:20 +02:00
|
|
|
* +LIBFOO_EXTRA_DOWNLOADS+ is a space-separated list of additional
|
|
|
|
files that Buildroot should download. If an entry contains +://+
|
|
|
|
then Buildroot will assume it is a complete URL and will download
|
|
|
|
the file using this URL. Otherwise, Buildroot will assume the file
|
|
|
|
to be downloaded is located at +LIBFOO_SITE+. Buildroot will not do
|
|
|
|
anything with those additional files, except download them: it will
|
2014-02-24 21:07:43 +01:00
|
|
|
be up to the package recipe to use them from +$(BR2_DL_DIR)+.
|
2013-10-08 20:17:00 +02:00
|
|
|
|
2012-06-17 13:54:00 +02:00
|
|
|
* +LIBFOO_SITE_METHOD+ determines the method used to fetch or copy the
|
|
|
|
package source code. In many cases, Buildroot guesses the method
|
|
|
|
from the contents of +LIBFOO_SITE+ and setting +LIBFOO_SITE_METHOD+
|
|
|
|
is unnecessary. When +HOST_LIBFOO_SITE_METHOD+ is not specified, it
|
|
|
|
defaults to the value of +LIBFOO_SITE_METHOD+. +
|
|
|
|
The possible values of +LIBFOO_SITE_METHOD+ are:
|
2014-12-19 08:12:33 +01:00
|
|
|
** +wget+ for normal FTP/HTTP downloads of tarballs. Used by
|
2012-06-17 13:54:00 +02:00
|
|
|
default when +LIBFOO_SITE+ begins with +http://+, +https://+ or
|
|
|
|
+ftp://+.
|
2014-12-19 08:12:33 +01:00
|
|
|
** +scp+ for downloads of tarballs over SSH with scp. Used by
|
2012-06-17 13:54:00 +02:00
|
|
|
default when +LIBFOO_SITE+ begins with +scp://+.
|
|
|
|
** +svn+ for retrieving source code from a Subversion repository.
|
2014-12-19 08:12:33 +01:00
|
|
|
Used by default when +LIBFOO_SITE+ begins with +svn://+. When a
|
2012-06-17 13:54:00 +02:00
|
|
|
+http://+ Subversion repository URL is specified in
|
|
|
|
+LIBFOO_SITE+, one 'must' specify +LIBFOO_SITE_METHOD=svn+.
|
|
|
|
Buildroot performs a checkout which is preserved as a tarball in
|
|
|
|
the download cache; subsequent builds use the tarball instead of
|
|
|
|
performing another checkout.
|
2013-09-11 14:12:05 +02:00
|
|
|
** +cvs+ for retrieving source code from a CVS repository.
|
|
|
|
Used by default when +LIBFOO_SITE+ begins with +cvs://+.
|
|
|
|
The downloaded source code is cached as with the +svn+ method.
|
2016-01-15 21:13:15 +01:00
|
|
|
Anonymous pserver mode is assumed otherwise explicitly defined
|
|
|
|
on +LIBFOO_SITE+. Both
|
|
|
|
+LIBFOO_SITE=cvs://libfoo.net:/cvsroot/libfoo+ and
|
|
|
|
+LIBFOO_SITE=cvs://:ext:libfoo.net:/cvsroot/libfoo+
|
|
|
|
are accepted, on the former anonymous pserver access mode is
|
|
|
|
assumed.
|
2013-09-11 14:12:05 +02:00
|
|
|
+LIBFOO_SITE+ 'must' contain the source URL as well as the remote
|
|
|
|
repository directory. The module is the package name.
|
2015-05-06 14:17:49 +02:00
|
|
|
+LIBFOO_VERSION+ is 'mandatory' and 'must' be a tag, a branch, or
|
|
|
|
a date (e.g. "2014-10-20", "2014-10-20 13:45", "2014-10-20
|
|
|
|
13:45+01" see "man cvs" for further details).
|
2014-12-19 08:12:33 +01:00
|
|
|
** +git+ for retrieving source code from a Git repository. Used by
|
2012-06-17 13:54:00 +02:00
|
|
|
default when +LIBFOO_SITE+ begins with +git://+. The downloaded
|
|
|
|
source code is cached as with the +svn+
|
|
|
|
method.
|
|
|
|
** +hg+ for retrieving source code from a Mercurial repository. One
|
|
|
|
'must' specify +LIBFOO_SITE_METHOD=hg+ when +LIBFOO_SITE+
|
|
|
|
contains a Mercurial repository URL. The downloaded source code
|
|
|
|
is cached as with the +svn+ method.
|
|
|
|
** +bzr+ for retrieving source code from a Bazaar repository. Used
|
|
|
|
by default when +LIBFOO_SITE+ begins with +bzr://+. The
|
|
|
|
downloaded source code is cached as with the +svn+ method.
|
2014-12-19 08:12:33 +01:00
|
|
|
** +file+ for a local tarball. One should use this when
|
2012-06-17 13:54:01 +02:00
|
|
|
+LIBFOO_SITE+ specifies a package tarball as a local filename.
|
|
|
|
Useful for software that isn't available publicly or in version
|
|
|
|
control.
|
2014-12-19 08:12:33 +01:00
|
|
|
** +local+ for a local source code directory. One should use this
|
2012-06-17 13:54:01 +02:00
|
|
|
when +LIBFOO_SITE+ specifies a local directory path containing
|
2014-12-19 08:12:33 +01:00
|
|
|
the package source code. Buildroot copies the contents of the
|
2012-06-17 13:54:01 +02:00
|
|
|
source directory into the package's build directory.
|
2011-10-10 10:46:39 +02:00
|
|
|
|
2017-02-07 12:08:17 +01:00
|
|
|
* +LIBFOO_GIT_SUBMODULES+ can be set to +YES+ to create an archive
|
|
|
|
with the git submodules in the repository. This is only available
|
|
|
|
for packages downloaded with git (i.e. when
|
|
|
|
+LIBFOO_SITE_METHOD=git+). Note that we try not to use such git
|
|
|
|
submodules when they contain bundled libraries, in which case we
|
|
|
|
prefer to use those libraries from their own package.

|
|
|
|
2015-07-11 16:15:05 +02:00
|
|
|
* +LIBFOO_STRIP_COMPONENTS+ is the number of leading components
|
|
|
|
(directories) that tar must strip from file names on extraction.
|
|
|
|
The tarball for most packages has one leading component named
|
|
|
|
"<pkg-name>-<pkg-version>", thus Buildroot passes
|
|
|
|
--strip-components=1 to tar to remove it.
|
|
|
|
For non-standard packages that don't have this component, or
|
|
|
|
that have more than one leading component to strip, set this
|
|
|
|
variable with the value to be passed to tar. Default: 1.
|
|
|
|
|
2015-10-24 14:48:53 +02:00
|
|
|
* +LIBFOO_EXCLUDES+ is a space-separated list of patterns to exclude
|
|
|
|
when extracting the archive. Each item from that list is passed as
|
|
|
|
a tar's +--exclude+ option. By default, empty.
|
|
|
|
|
2011-10-10 10:46:39 +02:00
|
|
|
* +LIBFOO_DEPENDENCIES+ lists the dependencies (in terms of package
|
|
|
|
name) that are required for the current target package to
|
|
|
|
compile. These dependencies are guaranteed to be compiled and
|
|
|
|
installed before the configuration of the current package starts. In
|
2012-11-27 12:59:16 +01:00
|
|
|
a similar way, +HOST_LIBFOO_DEPENDENCIES+ lists the dependencies for
|
2011-10-10 10:46:39 +02:00
|
|
|
the current host package.
|
|
|
|
|
2015-03-14 15:25:18 +01:00
|
|
|
* +LIBFOO_PATCH_DEPENDENCIES+ lists the dependencies (in terms of
|
|
|
|
package name) that are required for the current package to be
|
|
|
|
patched. These dependencies are guaranteed to be extracted and
|
|
|
|
patched before the current package is patched. In a similar way,
|
|
|
|
+HOST_LIBFOO_PATCH_DEPENDENCIES+ lists the dependencies for the
|
|
|
|
current host package.
|
|
|
|
This is seldom used; usually, +LIBFOO_DEPENDENCIES+ is what you
|
|
|
|
really want to use.
|
|
|
|
|
2014-05-15 19:37:04 +02:00
|
|
|
* +LIBFOO_PROVIDES+ lists all the virtual packages +libfoo+ is an
|
|
|
|
implementation of. See xref:virtual-package-tutorial[].
|
|
|
|
|
2011-10-10 10:46:39 +02:00
|
|
|
* +LIBFOO_INSTALL_STAGING+ can be set to +YES+ or +NO+ (default). If
|
|
|
|
set to +YES+, then the commands in the +LIBFOO_INSTALL_STAGING_CMDS+
|
|
|
|
variables are executed to install the package into the staging
|
|
|
|
directory.
|
|
|
|
|
|
|
|
* +LIBFOO_INSTALL_TARGET+ can be set to +YES+ (default) or +NO+. If
|
|
|
|
set to +YES+, then the commands in the +LIBFOO_INSTALL_TARGET_CMDS+
|
|
|
|
variables are executed to install the package into the target
|
|
|
|
directory.
|
|
|
|
|
2015-01-01 21:23:49 +01:00
|
|
|
* +LIBFOO_INSTALL_IMAGES+ can be set to +YES+ or +NO+ (default). If
|
|
|
|
set to +YES+, then the commands in the +LIBFOO_INSTALL_IMAGES_CMDS+
|
|
|
|
variable are executed to install the package into the images
|
|
|
|
directory.
|
|
|
|
|
2013-02-07 13:35:03 +01:00
|
|
|
* +LIBFOO_CONFIG_SCRIPTS+ lists the names of the files in
|
2013-01-30 03:46:40 +01:00
|
|
|
'$(STAGING_DIR)/usr/bin' that need some special fixing to make them
|
2013-02-07 13:35:03 +01:00
|
|
|
cross-compiling friendly. Multiple file names separated by space can
|
2013-02-07 13:35:04 +01:00
|
|
|
be given and all are relative to '$(STAGING_DIR)/usr/bin'. The files
|
|
|
|
listed in +LIBFOO_CONFIG_SCRIPTS+ are also removed from
|
|
|
|
+$(TARGET_DIR)/usr/bin+ since they are not needed on the target.

2012-01-11 18:53:41 +01:00
|
|
|
* +LIBFOO_DEVICES+ lists the device files to be created by Buildroot
|
|
|
|
when using the static device table. The syntax to use is the
|
2012-02-18 00:30:58 +01:00
|
|
|
makedevs one. You can find some documentation for this syntax in the
|
|

|
|
|
* +LIBFOO_PERMISSIONS+ lists the changes of permissions to be done at
|
|
|
|
the end of the build process. The syntax is once again the makedevs one.
|
2012-02-18 00:30:58 +01:00
|
|
|
You can find some documentation for this syntax in the xref:makedev-syntax[].
|
|
|
|
This variable is optional.
|
2012-01-11 18:53:41 +01:00
|
|
|
|
2013-04-12 09:14:18 +02:00
|
|
|
* +LIBFOO_USERS+ lists the users to create for this package, if it installs
|
2014-03-28 22:24:49 +01:00
|
|
|
a program you want to run as a specific user (e.g. as a daemon, or as a
|
2013-04-12 09:14:18 +02:00
|
|
|
cron-job). The syntax is similar in spirit to the makedevs one, and is
|
|
|
|
described in the xref:makeuser-syntax[]. This variable is optional.
|
|
|
|
|
2012-05-17 19:33:07 +02:00
|
|
|
* +LIBFOO_LICENSE+ defines the license (or licenses) under which the package
|
|
|
|
is released.
|
|
|
|
This name will appear in the manifest file produced by +make legal-info+.
|
2017-03-30 15:43:30 +02:00
|
|
|
If the license appears in https://spdx.org/licenses/[the SPDX License List],
|
|
|
|
use the SPDX short identifier to make the manifest file uniform.
|
2012-05-17 19:33:07 +02:00
|
|
|
Otherwise, describe the license in a precise and concise way, avoiding
|
|
|
|
ambiguous names such as +BSD+ which actually name a family of licenses.
|
|
|
|
This variable is optional. If it is not defined, +unknown+ will appear in
|
2016-01-25 06:05:40 +01:00
|
|
|
the +license+ field of the manifest file for this package. +
|
|
|
|
The expected format for this variable must comply with the following rules:
|
|
|
|
** If different parts of the package are released under different
|
|
|
|
licenses, then +comma+ separate licenses (e.g. +`LIBFOO_LICENSE =
|
2017-03-30 15:43:30 +02:00
|
|
|
GPL-2.0+, LGPL-2.1+`+). If there is clear distinction between which
|
2016-01-25 06:05:40 +01:00
|
|
|
component is licensed under what license, then annotate the license
|
|
|
|
with that component, between parenthesis (e.g. +`LIBFOO_LICENSE =
|
2017-03-30 15:43:30 +02:00
|
|
|
GPL-2.0+ (programs), LGPL-2.1+ (libraries)`+).
|
2016-01-25 06:05:40 +01:00
|
|
|
** If the package is dual licensed, then separate licenses with the
|
2017-03-30 15:43:30 +02:00
|
|
|
+or+ keyword (e.g. +`LIBFOO_LICENSE = AFL-2.1 or GPL-2.0+`+).
|
2012-05-17 19:33:07 +02:00
|
|
|
|
|
|
|
* +LIBFOO_LICENSE_FILES+ is a space-separated list of files in the package
|
|
|
|
tarball that contain the license(s) under which the package is released.
|
|
|
|
+make legal-info+ copies all of these files in the +legal-info+ directory.
|
|
|
|
See xref:legal-info[] for more information.
|
|
|
|
This variable is optional. If it is not defined, a warning will be produced
|
|
|
|
to let you know, and +not saved+ will appear in the +license files+ field
|
|
|
|
of the manifest file for this package.
|
|
|
|
|
2015-10-03 23:18:21 +02:00
|
|
|
* +LIBFOO_ACTUAL_SOURCE_TARBALL+ only applies to packages whose
|
|
|
|
+LIBFOO_SITE+ / +LIBTOO_SOURCE+ pair points to an archive that does
|
|
|
|
not actually contain source code, but binary code. This a very
|
|
|
|
uncommon case, only known to apply to external toolchains which come
|
|
|
|
already compiled, although theoretically it might apply to other
|
|
|
|
packages. In such cases a separate tarball is usually available with
|
|
|
|
the actual source code. Set +LIBFOO_ACTUAL_SOURCE_TARBALL+ to the
|
|
|
|
name of the actual source code archive and Buildroot will download
|
|
|
|
it and use it when you run +make legal-info+ to collect
|
|
|
|
legally-relevant material. Note this file will not be downloaded
|
|
|
|
during regular builds nor by +make source+.
|
|
|
|
|
|
|
|
* +LIBFOO_ACTUAL_SOURCE_SITE+ provides the location of the actual
|
|
|
|
source tarball. The default value is +LIBFOO_SITE+, so you don't
|
|
|
|
need to set this variable if the binary and source archives are
|
|
|
|
hosted on the same directory. If +LIBFOO_ACTUAL_SOURCE_TARBALL+ is
|
|
|
|
not set, it doesn't make sense to define
|
|
|
|
+LIBFOO_ACTUAL_SOURCE_SITE+.
|
|
|
|
|
2012-11-27 12:59:17 +01:00
|
|
|
* +LIBFOO_REDISTRIBUTE+ can be set to +YES+ (default) or +NO+ to indicate if
|
|
|
|
the package source code is allowed to be redistributed. Set it to +NO+ for
|
|
|
|
non-opensource packages: Buildroot will not save the source code for this
|
|
|
|
package when collecting the +legal-info+.
|
|
|
|
|
2013-06-06 00:47:30 +02:00
|
|
|
* +LIBFOO_FLAT_STACKSIZE+ defines the stack size of an application built into
|
|
|
|
the FLAT binary format. The application stack size on the NOMMU architecture
|
|
|
|
processors can't be enlarged at run time. The default stack size for the
|
|
|
|
FLAT binary format is only 4k bytes. If the application consumes more stack,
|
|
|
|
append the required number here.
|
|
|
|
|
2011-10-10 10:46:39 +02:00
|
|
|
The recommended way to define these variables is to use the following
|
|
|
|
syntax:
|
|
|
|
|
|
|
|
----------------------
|
|
|
|
LIBFOO_VERSION = 2.32
|
|
|
|
----------------------
|
|
|
|
|
|
|
|
Now, the variables that define what should be performed at the
|
|
|
|
different steps of the build process.
|
|
|
|
|
2013-08-06 23:36:20 +02:00
|
|
|
* +LIBFOO_EXTRACT_CMDS+ lists the actions to be performed to extract
|
|
|
|
the package. This is generally not needed as tarballs are
|
|
|
|
automatically handled by Buildroot. However, if the package uses a
|
|
|
|
non-standard archive format, such as a ZIP or RAR file, or has a
|
|
|
|
tarball with a non-standard organization, this variable allows to
|
|
|
|
override the package infrastructure default behavior.
|
|
|
|
|
2012-11-27 12:59:16 +01:00
|
|
|
* +LIBFOO_CONFIGURE_CMDS+ lists the actions to be performed to
|
|
|
|
configure the package before its compilation.
|
2011-10-10 10:46:39 +02:00
|
|
|
|
2012-11-27 12:59:16 +01:00
|
|
|
* +LIBFOO_BUILD_CMDS+ lists the actions to be performed to
|
|
|
|
compile the package.
|
2011-10-10 10:46:39 +02:00
|
|
|
|
2012-11-27 12:59:16 +01:00
|
|
|
* +HOST_LIBFOO_INSTALL_CMDS+ lists the actions to be performed
|
2011-10-10 10:46:39 +02:00
|
|
|
to install the package, when the package is a host package. The
|
|
|
|
package must install its files to the directory given by
|
|
|
|
+$(HOST_DIR)+. All files, including development files such as
|
|
|
|
headers should be installed, since other packages might be compiled
|
|
|
|
on top of this package.
|
|
|
|
|
2012-11-27 12:59:16 +01:00
|
|
|
* +LIBFOO_INSTALL_TARGET_CMDS+ lists the actions to be
|
2011-10-10 10:46:39 +02:00
|
|
|
performed to install the package to the target directory, when the
|
|
|
|
package is a target package. The package must install its files to
|
|
|
|
the directory given by +$(TARGET_DIR)+. Only the files required for
|
2012-11-27 12:59:17 +01:00
|
|
|
'execution' of the package have to be
|
|
|
|
installed. Header files, static libraries and documentation will be
|
|
|
|
removed again when the target filesystem is finalized.
|
2011-10-10 10:46:39 +02:00
|
|
|
|
2012-11-27 12:59:16 +01:00
|
|
|
* +LIBFOO_INSTALL_STAGING_CMDS+ lists the actions to be
|
2011-10-10 10:46:39 +02:00
|
|
|
performed to install the package to the staging directory, when the
|
|
|
|
package is a target package. The package must install its files to
|
|
|
|
the directory given by +$(STAGING_DIR)+. All development files
|
|
|
|
should be installed, since they might be needed to compile other
|
|
|
|
packages.
|
|
|
|
|
2014-05-09 02:20:11 +02:00
|
|
|
* +LIBFOO_INSTALL_IMAGES_CMDS+ lists the actions to be performed to
|
|
|
|
install the package to the images directory, when the package is a
|
|
|
|
target package. The package must install its files to the directory
|
|
|
|
given by +$(BINARIES_DIR)+. Only files that are binary images (aka
|
|
|
|
images) that do not belong in the +TARGET_DIR+ but are necessary
|
|
|
|
for booting the board should be placed here. For example, a package
|
|
|
|
should utilize this step if it has binaries which would be similar
|
|
|
|
to the kernel image, bootloader or root filesystem images.
|
|
|
|
|
2012-11-27 12:59:16 +01:00
|
|
|
* +LIBFOO_INSTALL_INIT_SYSV+ and +LIBFOO_INSTALL_INIT_SYSTEMD+ list the
|
|
|
|
actions to install init scripts either for the systemV-like init systems
|
2012-07-28 09:21:22 +02:00
|
|
|
(busybox, sysvinit, etc.) or for the systemd units. These commands
|
|
|
|
will be run only when the relevant init system is installed (i.e. if
|
|
|
|
systemd is selected as the init system in the configuration, only
|
|
|
|
+LIBFOO_INSTALL_INIT_SYSTEMD+ will be run).
|
|
|
|
|
2016-06-04 18:30:47 +02:00
|
|
|
* +LIBFOO_HELP_CMDS+ lists the actions to print the package help, which
|
|
|
|
is included to the main +make help+ output. These commands can print
|
|
|
|
anything in any format.
|
|
|
|
This is seldom used, as packages rarely have custom rules. *Do not use
|
|
|
|
this variable*, unless you really know that you need to print help.
|
|
|
|
|
2011-10-10 10:46:39 +02:00
|
|
|
The preferred way to define these variables is:
|
|
|
|
|
|
|
|
----------------------
|
|
|
|
define LIBFOO_CONFIGURE_CMDS
|
|
|
|
action 1
|
|
|
|
action 2
|
|
|
|
action 3
|
|
|
|
endef
|
|
|
|
----------------------
|
|
|
|
|
|
|
|
In the action definitions, you can use the following variables:
|
|
|
|
|
2016-12-02 03:41:52 +01:00
|
|
|
* +$(LIBFOO_PKGDIR)+ contains the path to the directory containing the
|
|
|
|
+libfoo.mk+ and +Config.in+ files. This variable is useful when it is
|
2015-11-04 23:11:23 +01:00
|
|
|
necessary to install a file bundled in Buildroot, like a runtime
|
2015-11-05 00:10:50 +01:00
|
|
|
configuration file, a splashscreen image...
|
2015-11-04 23:11:23 +01:00
|
|
|
|
2011-10-10 10:46:39 +02:00
|
|
|
* +$(@D)+, which contains the directory in which the package source
|
|
|
|
code has been uncompressed.
|
|
|
|
|
|
|
|
* +$(TARGET_CC)+, +$(TARGET_LD)+, etc. to get the target
|
|
|
|
cross-compilation utilities
|
|
|
|
|
|
|
|
* +$(TARGET_CROSS)+ to get the cross-compilation toolchain prefix
|
|
|
|
|
|
|
|
* Of course the +$(HOST_DIR)+, +$(STAGING_DIR)+ and +$(TARGET_DIR)+
|
|
|
|
variables to install the packages properly.
|
|
|

Finally, you can also use hooks. See xref:hooks[] for more information.
